STOVE-GRATE.

SPECIFICATION forming pere of Lettere Patent No. 293,296, aerea February12, 18er.. Application filed May 14, 1883. (No model.)

of Massachusetts, a citizen of the United States,

have invented a certain new and useful Improvementof Stove-Grates, ofwhich the following is afull, clear, and exact description,

reference being had to the accompanying drawings, forming a part of thisspecification, in

explaining its nature, in which- Figure 1 is a plan view of a gratehaving my improved construction. Fig. 2 is an end elevation thereof.Fig. 3 is a vertical section on the line x 00 of Fig. l. Fig. 4eillustrates a modified form of the invention, wherein only the upperportion of the grate is used. Fig.

5 is a vertical section upon theline yy of Fig. el.

This invention is an improvement upon that described in my LettersPatent No. 229,852, dated July 13, 1880. The especial form or shape ofthe grate described in said patent is circular, and my present inventionrelates to means whereby I am enabled to use substantially the sameprinciple of construction therein described in a rectangular or squaregrate; and it consists in various details of construction whereby thisresult is accomplished.

Referring to the drawings, A4 represents the grate-frame; c, the frontand rear bars of the main grate; c', the end bars thereof. These.

front and back and end bars Vare pivoted to each other at chaud the endbars are pivoted to the grate-frame A and to the crosspiece or plate ciat at `Each of the grate-bars has projections or fingers c5, extendingdownwardly and inwardly to the opening B. vThe corneriingers, a, areshaped as represented in Fig. l, so that the movement of the gratecannot be interfered with by means of coals or cinders lodging betweenthe fingers at the corne-rs.- By means ofthe lever or arm B', or in anyother desirable way, the grate'is reciprocated laterally upon the pivotsa4. This causes each ofthe back and front and ofthe end bars to be movedin opposite directions, and a very effective shaking action is thusprovided. `Of course, the opening B may be-nearer the back of the grate,as represented in the drawings, or it may becentrally located, or at thefront. I prefer generally, however, as the front portion of the fire ismore easily reached by the more inclined than those upon the front,thereby throwing the opening B toward the back, as by so doing a smallersupport is provided for the lire at the back, and consequently, upon areciprocation of the grate, the ashes at` thatportion of the iire willsettle more rapidly upon the under grate, and thus .clear the fire morequickly than if the iingers or projections were longer andless.inclined, and the back: of the fire will therefore require lessattention.

Below the opening B, I arrange the under grate, G, which may be solid,as represented in the drawings, or may have openings across it. Itpreferably is pivoted to dump toward the front of the ash-pit, and it issupported by the cross-bar or'rod b, the ends of which form pivots b,which are supported by the poker, to make the fingers upon the back barbrackets b2, attached to the grate-frame. This l grate is dumped orturned by means of 'a lever attached to one end of the rod b., and anarm which extends from the end of the lever, preferably to without thestove, through a slot in the casing,.or in any other desirable way. i

Between the lower and the upper grate is the anti-clinlrer space D.There may be arranged between the bars a a of the grate and thegrate-frame a space, e, so that the uppen and lower surfaces of the endand back bars shall not come in contact therewith, in which case theframe may have projections c', extending downwardly and upwardlytherefrom that shall come in contact with the upper and lower surfacesofthe grate-bars.

I do not confine myself to the especial means for connecting or pivotingtogether the ends of the bars, neither do I limit myself to the exactmethod of hanging it specified, and I may use any mechanicalAequivalents for the specific methods herein described without departingfrom the spirit of the invention. It is ofcourse obvious that byreducing the size of the opening in the upper grate the lower grate maybe entirely dispensed with.; but I do not prefer this construction. 4

In Figs. 4e and 5 the iingers c5 of the upper -grate are shown extendedvery nearly across the opening d3, and they may be shaped as shown inFig. 3that is, the upper portion thereof may be inclined and thelowerportion IOO ,ables me to dispense with the lower section, 0, of thegrate.

horizontal, as desired, or they may be entirely inclined or horizontal.This construction en- I am aware of the Patent No. 34,731, to Brown,dated May 25, 1862, and I do not claizn anything therein described; nordo I consider that it contains the features of my invention, in that itdoes not describe a grate having four bars pivoted 4together at theirends and to the grate-frame, as above described, and having iingerswhich project inward therefrom to form the hre-supporting surface. It

will be noticed that this construction divides the grate into foursections-namely, the front and back and the two end-and that eachsection has a movement in a direction the reverse of the movement of theone opposite it, and that, therefore, by this movement, the re isWell-broken and shaken at the end as well as at the center.

Having thus fully described my invention, I claim and desire to secureby Letters Patl ent of the United Statesl. Astove-grate havingtheparallel sidebars, a, and the parallel end bars, a', thev end bars beingpivoted to the frame, of the grate, as described, and the side barsbeing pivoted to the end bars at c2, the said bars having the fingers a5projecting inwardly therefrom, all substantially as and for th epurposes described.

2. A stove or furnace provided with a rectangular or square grate,consisting of the lingered bars a a', surrounding the opening B, adaptedto be reciprocated, as speciiied, and the grate C below said opening B,capable of being tipped toward the ash-pit door, and a clearing-space,D, between the upper surface and the lower surface of the upper grate,substantially as and for the purposes specied.

3. The combination, in a grate, ofthe fingered grate-bars a a', pivotedto each other and to the grate-frame, as specified, surrounding theopening B, and adapted to be moved or reciprocated in relation to eachother as indicated, with the grate C below said opening B, allsubstantially as and for the purposes described.

4. In a grate, the combination of the fingered bars a fa, pivoted toeach other and to the grateframe surrounding the opening B, the fingersc of the back bar being more inclined than those f ofthe front, andadapted to be moved or reciproeated in relation to each other asindicated, with the grate C, arranged below said opening B, allsubstantially as and for the purposes described.
